Abstract
The study aims to identify the infiltration characteristics of the soil of the Bashiqa region. This was done by identifying (18) sites distributed over the study area that were chosen on natural grounds. Experiments were conducted to measure infiltration in the field using a cylindrical plunger. Soil infiltration rates were measured in each site. The selected sites in the study area and during the specified time periods, which were each of (1, 2, 3, 4, 5, 6, 7, 8, 16, 32, 64, 90, 120) minutes, which included the initial infiltration rate and the infiltration rate. Cumulative, and the results of the field work analysis of the infiltration experiments after applying the Kostakov equation during (120) minutes showed that the values of the initial infiltration depth varied between (0.004) cm/minute in the sites of (Qulan Tappe, Klija, Bukhai, Hassan Shami, and Orta Kharab) as the lowest percentage. The highest rate was 0.020 cm/min at the Bahzani site with an average of 0.0068%, and the values of the cumulative infiltration depth varied between 1.314 cm/min at the Jabal Bashiqa site the lowest rate and 5.360 cm/min. On the site (Bahzani) the highest percentage with an average of (2.49761)%
